Abstract

The invention relates to the technical field of waste gas purification, and particularly relates to a plastic granulation waste gas treatment system and a waste gas treatment process. The system includes two stages of spraying oil separating columns, a filtration tank, an oil fume purifier and a photocatalytic oxidation device which are connected in order. The two stages of spraying oil separatingcolumns include a first-stage spraying oil separating column and a second-stage spraying oil separating column. The system and the process are simple, can efficiently treat peculiar-smell gas in plastic granulation, perform staged treatment and purification for different components, and are high in purification efficiency, resistant to impact load, relatively low in investment and free of secondary pollution. Waste gas purification effects can meet environment protection requirements.

Description

technical field [0001] The invention relates to the technical field of waste gas purification treatment, in particular to a plastic granulation waste gas treatment system and a waste gas treatment process. Background technique [0002] The main production links of waste gas such as PVC sheets, PC sheets, and plastic granulation are processes such as plastic heating and sheet rolling. The main pollutants are oil, non-methane total hydrocarbons, etc. The odor composition of exhaust gas is complex and changeable. [0003] The VOC concentration in the exhaust gas is about 200mg / m 3 , The odor concentration is about 10000 (dimensionless). [0004] Exhaust gas emission implements GB16297-96 "Comprehensive Emission Standard of Air Pollutants" and GB14554-93 "Emission Standard of Odor Pollutants". [0005] In the existing waste gas treatment process of the plastic granulation production line, the commonly used process methods are mainly to use filter cotton to remove oil, activa...
